Area Forecast Discussion...UPDATED
National Weather Service Twin Cities/Chanhassen MN
556 AM CST Thu Dec 7 2017

.SHORT TERM...(Today and tonight)
Issued at 350 AM CST Thu Dec 7 2017

Clouds are on their way out this morning as the trough slides
southeast and ridging builds in. The clearing will last for the
day until clouds increase tonight ahead of the next system diving
south for Friday. Winds will finally be weaker today than the past
few days. This will make it feel milder, but the shallower mixing
and snow cover should keep temps from mixing into the mid 20s as
temps aloft would otherwise indicate.

WAA tonight and some moisture in the DGZ may generate a few
flurries. The abundance of dry air above and below this layer
will keep any accumulation from occurring.

.LONG TERM...(Friday through Wednesday)
Issued at 350 AM CST Thu Dec 7 2017

Low pressure will track from northwest MN to western or central WI
Friday afternoon, to Lake Michigan by Friday night. Areas along and
east of the track will see a period of snow, while to the west only
a few flurries will fall. An inch or two are forecast from this
quick mover, roughly east of I-35.

The pattern changes very little for the next 10 days. The deep trough
to the east and the anomalously large ridge to the west will maintain
a northwest flow for the Upper Midwest. Several clipper systems
will migrate southeastward, every one capable of some accumulating
snow in a relatively narrow corridor. These should occur Sunday
night/Monday, Tuesday/Tuesday night, and Wednesday/Wednesday

Temperatures will generally bounce in the near normal range
locally, with some variation up or down depending where each
system tracks.
